PROBLEM TO BE SOLVED: To favorably conduct steering control along a set route to the utmost, while reducing a cost using an inexpensive gyro device, by using effectively positional information of a vehicular body found by a GPS positional information calculating means. SOLUTION: This travel controller for the working vehicle is provided with the GPS positional information calculating means 100 for finding the positional information of the vehicular body, the gyro device 57 for detecting azimuth displacement information of the vehicular body, and a gyro information determining means 103 for determining a gyro information proper state where the azimuth displacement information of the vehicular body is detected properly by the gyro device 57, or a gyro information improper state where it is not detected properly, the steering control is conducted based on the positional information of the vehicular body found by the GPS positional information calculating means 100 and the azimuth displacement information of the vehicular body detected by the gyro device 57, when the gyro information proper state is detected, and the steering control is conducted based on only the positional information of the vehicular body found by the GPS positional information calculating means 100, when the gyro information improper state is detected.
